Phylogenetic relationships among nucleotide sequences of barcode regions of small subunit ribosomal RNA (SSU rRNA) of Blastocystis sp. The neighbor-joining method was used to construct the trees by the Kimura-2-parameter model. The numbers on the branches are percent bootstrapping values from 1000 replicates, with values > 50% shown in the tree. Each sequence is identified by its subtypes, hosts, accession number, and country. Blastocystis subtypes identified in the present study are indicated in bold type
